Combining nuclei requires much higher temperatures than splitting nuclei. It will also release three neutrons and nuclear energy.Īn example of two nuclei combining is the combination of two hydrogen nuclei to form a helium nucleus and nuclear energy. As uranium-236 is unstable, it will split into two smaller nuclei such as barium and krypton. Uranium-236 can be formed by bombarding uranium-235 with slow-moving neutrons.
Uranium-236 is an example of an unstable isotope. Large nuclei split when they are unstable. We can see from options (A) and (B) that one of these processes involves large nuclei splitting and the other involves small nuclei combining. Nuclear fusion and nuclear fission are both processes which release a lot of energy.
Or (B) in nuclear fusion, large nuclei split, while in nuclear fission, small nuclei combine. The short answer questions are conceptual and meant to see if the students are able to apply what they've learned in the unit.Which of the following statements correctly contrasts nuclear fusion and nuclear fission? (A) In nuclear fission, large nuclei split, while in nuclear fusion, small nuclei combine. The vocabulary words can be found scattered throughout the different instructional worksheets from this unit. The study guide is divided into two sections: vocabulary and short answer questions. Purpose: Once the instruction for the unit is completed, students can complete this study guide to aid in their preparation for a written test. Nuclear Energy Study Guide View Worksheet In this lab, students will use colored water to simulate the decay of Strontium-90, while doing some calculations to see how long it takes the radioactive isotope to become harmless.Įssential concepts: Nuclear waste, radioactive half-life. Spent fuel has been accumulating in dry cask storage at the world's nuclear facilities for decades, and no long-term disposal plan has established by the scientific community.

Purpose: One of the biggest challenges facing nuclear energy is the problem of how to deal with the waste. Nuclear Waste Half-Life Lab View Worksheet Students will use the periodic table to predict the alpha and beta decay products of different radioactive elements.Įssential Concepts: Radioactive decay, alpha particles, beta particles. Purpose: This is a worksheet of radioactive decay practice problems. Cockroaches, flour beetles, and fruit flies are all exposed to varying levels of radiation and their survival tracked over a period of 30 days.Įssential Concepts: Radioactive decay, radioactive fallout, acute, chronic, alpha particles, beta particles, gamma rays.Īlpha and Beta Decay Worksheet View Worksheet Purpose: This episode of Mythbusters tries to answer the question of whether cockroaches could really survive a nuclear disaster or war. Mythbusters - Radiation and Cockroaches Worksheet View Worksheet
This episode covers the conditions that led to the birth of the sun, the nuclear fusion within that fuels it, sunspots, solar flares, and the predicted eventual death of the sun.Įssential Concepts: Nuclear fusion, radiation, convection, sunspots, solar flares. Purpose: This is a worksheet to accompany the Secrets of the Sun episode of the Universe documentary series. The Universe - Secrets of the Sun View Worksheet These are helpful to use if you have students who struggle with effective note-taking and either write nothing down at all or try to write everything (and fail to listen to actual lecture). Purpose: This is a fillable notes outline to accompany the nuclear energy Powerpoint. Nuclear Chemistry Student Notes Outline View Worksheet Students will then learn about both nuclear fusion and fission within the context of the sun, fission nuclear reactors, and nuclear weapons.Įssential Concepts: Nucleus, protons, neutrons, radioactive decay, radioactive fallout, fission, fusion, nuclear energy, nuclear meltdowns, half-life. Purpose: This Powerpoint lecture gives a brief history of the discovery and application of radioactivity, including Becquerel's discovery and Rutherford's gold foil experiment. Nuclear Chemistry Powerpoint Lecture View Powerpoint Nuclear fission, fusion, and decay all primarily involve changes to the composition of the nucleus of the atom, so students will be able to apply what they know about protons, neutrons, and atomic mass. Having been introduced to the basic structure of atoms and the use of the periodic table, this is an opportune time to introduce basic nuclear chemistry.
